Abstract
Binary complex salts [Ru(NH3)5Cl][ReCl6] and [Ru(NH3)5Cl]2[ReCl6]Cl2 were synthesized and characterized. An X-ray diffraction analysis showed that they were isostructural with the previously obtained isoformula salts [Rh(NH3)5Cl]×[OsCl6] and [Ir(NH3)5Cl]2[PtCl6]Cl2, respectively. Thermolysis of these compounds under hydrogen and helium was studied. According to X-ray phase analysis data, bimetallic solid solutions Ru0.67Re0.33 and Ru0.50Re0.50 were the final products of thermolysis. Their unit cell parameters correspond to the characteristics of alloys with similar compositions.
